as for pressure on your stomach while you sleep pushing acid etc. - that sounds like something losing weight would solve.

when men get older most of their fat is stored viscerally ( as opposed to babies who store fat under the skin or women who store it on their hips ).  i can see how this could be pushing on your stomach.

losing weight would be worth it for you regardless of what is causing what.

trying carnivore may or may not reveal any benefits.

maybe lose weight first if you still have stomach issues then try carnivore.

or maybe trying carnivore will help you lose weight.

my only issues with carnivores is their lies that they don't need Vitamin C and that calories don't count.  so my problem is with Carnivores ( scum ) not with Carnivore diet ( decent, when supplemented with Vitamin C ) 

 most animals - both Carnivores and Herbivores - can synthesize their own Vitamin C.

Humans are one of the few species who can't - we need Vit C in the diet.

Carnivores deny this because it complicates their propaganda ...

but with added synthetic Vitamin C ( Ascorbic Acid is so cheap it is a popular for cleaning swimming pools for example ) Carnivore becomes viable.

5 years worth of Vitamin C bought as bulk Ascorbic Acid is less than $20.

If you have money it's better to only buy 1 year's worth as it will slightly degrade overtime depending on how you store it.  5 years is pushing it in terms of shelf life.
